Selecting the right material is critical for safety and durability. For heavy-duty welding, prioritize split cowhide leather due to its superior heat resistance and spark protection. For chemical handling, look for PVC, Nitrile, or Neoprene coatings that meet EN 14605 standards. In food processing, TPU (Thermoplastic Polyurethane) is preferred as it is lightweight, microbial-resistant, and FDA-compliant. For general workshops, 12oz to 16oz waxed canvas provides an excellent balance of water resistance and mechanical durability.
